Description

Automatic combination device for sterilizing whole vehicle and killing cold chain products

Technical Field

The invention relates to the technical field of sterilizing equipment, in particular to an automatic combined device for sterilizing a whole vehicle and sterilizing a cold chain product.

Background

New coronavirus is abused in 2019, and although various governments and nationwide people pay huge efforts, the positive detection of new coronavirus nucleic acid by imported cold chain food and cold chain food transportation tools frequently appears, so that epidemic prevention work is still very serious. The new coronavirus can survive in a low-temperature environment of-80 ℃ to a high-temperature environment of 50 ℃, for example, the new coronavirus or an infected person exists in a food processing, transporting, selling or storing environment, and the whole production, processing and circulation links of cold chain food have the possibility of being polluted, so that the equipment for cold chain disinfection is urgent.

At present, no report is found on disinfection equipment for cold chain food and transportation vehicles thereof. The disinfection of cold chain products can only be realized by spraying disinfection on a container and then enabling an operator to enter the container to transport cold chain food to a conveyor belt, spraying disinfection solution on the cold chain food, and adopting a manual transportation disinfection mode, which is troublesome and laborious. The spraying disinfection can only kill the virus on the outer surface of the package, and has no killing effect on the virus in the cold chain food. In addition, the spraying disinfectant has the risk of chemical pollution to cold chain products, particularly cold chain foods, and the sprayed chemical disinfectant can generate a precooling and crystallization phenomenon after meeting the cold chain products, so that the disinfection effect cannot be exerted. The manual spraying disinfection is adopted for the container vehicle, the disinfection time is long, the vehicle bottom disinfection is not thorough, and the sterilization dead angle exists.

The existing disinfection mode has great limitation, such as: physical heating methods cannot be used for cold chain cargo; the ultraviolet disinfection and sterilization can only disinfect the surfaces of articles, but cannot disinfect the articles in the packaging box; ozone sterilization needs to be performed in an unmanned environment, needs to maintain high ozone concentration, has long sterilization time, cannot sterilize the inside of a packaged object, and is not suitable for a cold chain system. In addition, the chemical disinfectant can not exert the disinfecting and sterilizing effect when meeting the frozen crystallization of the disinfectant which is easy to spray in a low-temperature cold chain product, so that most of the chemical disinfectant can not disinfect and lose efficacy on the cold chain product, and in addition, the chemical reagent has large influence on the food quality, even has residual toxicity, has non-ideal effect, consumes too much energy, is not friendly to the environment and other factors, so people are forced to urgently want to research and discover novel and efficient disinfecting and sterilizing technologies and equipment.
